Unreleased

Changed

• Update embedded-hal alpha support to version 1.0.0-alpha.9 - @jannic (Non-blocking traits were moved to embedded-hal-nb, which is not yet supported)
• Implement UartConfig::new constructor method - @jannic
• Deprecate uart::common_configs - @jannic
• Fix spelling error in UART error discarded field - @Sizurka
• Fix contents of UART error discarded field - @Sizurka
• Fix watchdog counter load value - @Sizurka
• Fix concurrent accesses to sm_execctrl and sm_instr when sideset isn't optional - @ihtinuel
• pio: Move interrupt related (en|dis)abling/forcing methods to the statemachine - @ithinuel
• Mark Timer & Alarm* Send and Sync - @ithinuel
• The feature critical-section-impl is now enabled by default from the BSP crates - @jannic
• Simplify signature of Alarm::schedule, removing generic parameter - @ithinuel
• USB: Use the dedicated write_bitmask_* functions - @ithinuel

Added

• Add rtic-monotonic support for timer & alarms (feature gated) - @ithinuel
• Add SPI is_busy function - @papyDoctor
• Add set_fifos/set_rx_watermark/set_tx_watermark - @papyDoctor
• Add a method to allow setting the PIO's clock divisor without floats - @ithinuel
• Use TimerInstant in Timer::GetCounter & add Alarm::schedule_at - @ithinuel

0.6.0 - 2022-08-26

Added

• Documentation Example for the bsp_pin! macro - @ hmvp
• Timer: Documentation & doc examples for Timers - @9names
• Add suspend, resume and remote wakeup support. - @ithinuel & @jannic
• rp2040-e5 feature enabling the workaround for errata 5 on the USB device peripheral. - @ithinuel
• NonPwmPinMode for gpio::Disabled - @FlorianUekermann
• RAM-based interrupt vector tables - @9names
• Support for critical-section 1.0.0. Critical-section 0.2 is still supported (ie. a custom-impl is provided, compatible with the 1.0.0 implementation), to avoid a breaking change. It will be removed later. - @jannic
• Add support for the Interpolator. @fenax

Changed

• Update dev dependencies on cortex-m-rtic to 1.1.2 - @jannic
• Use correct interrupt names in timer::alarms - @hmvp
• Update embedded-hal alpha support to version 1.0.0-alpha.8 - @jannic
• Fix PIO rx fifo status - @jannic
• Implement From<&SomeClock> for Hertz instead of From<SomeClock> for Hertz for the clocks in rp2040_hal::clocks. - @jannic
• Fix i2c example using the wrong clock. - @jannic
• Fix duty cycle handing on disabled pwm channels. - @jannic
• GPIO IRQ example: add check for interrupt source - @9names
• Align USB synchronisation requirements with the manual & pico-sdk - @ithinuel
• Update dependencies on usb-device to 0.2.9 - @ithinuel
• Use wfi in otherwise empty infinite loops in examples. - @jannic
• Use generic bootloader in examples - @jannic & @ithinuel
• Use rp2040-hal's entry function. - @ithinuel
• Migrate from embedded-time to fugit - @ithinuel
• Fix PIO's set_pins and set_pindirs when out_sticky is set. - @jannic & @ithinuel
• Clarify usage of boot2 section - @a-gavin

Removed

• Unnecessary cortex_m::interrupt::free in timer.rs - @jannic
• Unused embassy-traits deps - @9names

0.5.0 - 2022-06-13

MSRV

The Minimum-Supported Rust Version (MSRV) for this release is 1.61

Added

• RP2040 specific #[entry] macro that releases spinlocks - @jannic
• Start multiple state machines in sync with each other - @astraw
• Unsafe fn for freeing all spinlocks when you can't use the RP2040 entry macro (eg RTIC) - @9names
• Optional feature for enabling defmt formatting for i2c errors - @ithinuel
• Accessor for getting the offset of an installed PIO program - @fenax

Changed

• Use thread send safe UART* marker when splitting, improves UART ergonmics - @marius-meissner
• Improve performance for hardware division instrinsics. Internal intrinsics cleanup - @Sizurka
• Provide a better alarm abstraction - @ithinuel
• Update Multicore::spawn to be able to take a closure without requiring alloc. Improve Multicore ergonomics and add example for how to use new API - @Liamolucko
• Allow PIO program to be 32 instructions long, was previously limited to 31 - @jannic
• Fix Typos - @mqy, @danbev
• Replace generic pio::Tx::write with write_u8_replicated, write_u16_replicated, and update write to take a u32. The generic version was too easy to misuse. - @9names
